Platelet preparations, including platelet-rich plasma and platelet-rich fibrin matrix, have been used to improve wound healing, recovery time, and cosmetic outcomes for facial rejuvenation. Bioactive growth factors released from platelets are the putative agents in producing a reparative tissue reaction in the treated area. Different methods of processing the patients' blood will yield different types of platelet preparations with different components and properties, and it is important to understand these differences and their potential implications.

Purpose: A linear surgical scar, when located in the head and neck region, can be a significant cosmetic concern. Laser skin resurfacing with a fractional laser and a pulsed dye laser has been proven to be useful for treating such scars. As alternatives, we used a classic ablative CO laser in continuous mode with a 1-mm spot size and a 595-nm Nd:YAG laser. Read More

Topical anaesthetic cream (TAC) is commonly used as a pre-treatment of ablative fractional resurfacing (AFR) laser. Most of anaesthetic cream contains distilled water as major component. Therefore, pre-operative TAC may interfere the photothermal reaction in the skin treated with fractional carbon-dioxide (FCO) laser and fractional erbium-doped yttrium aluminium garnet (FEr:YAG) laser.

Facial scars can be caused by a traumatic event or indeed surgical procedures. Several treatment modalities have been suggested including surgical or resurfacing techniques, autologous fat transfer, and injection of fillers. However, these approaches have varying degrees of success and associated side effects. Read More

As known, fractional CO resurfacing treatments are more effective than non-ablative ones against aging signs, but post-operative redness and swelling prolong the overall downtime requiring up to steroid administration in order to reduce these local systems. In the last years, an increasing interest has been focused on the possible use of probiotics for treating inflammatory and allergic conditions suggesting that they can exert profound beneficial effects on skin homeostasis. In this work, the Authors report their experience on fractional CO laser resurfacing and provide the results of a new post-operative topical treatment with an experimental cream containing probiotic-derived active principles potentially able to modulate the inflammatory reaction associated to laser-treatment.

Importance: The removal of café-au-lait macules (CALMs) in patients with darker skin phototypes poses a significant challenge due to limited available therapeutic options and increased risk of adverse effects, including permanent scarring and further dyspigmentation. Herein, we demonstrate the novel use of non-ablative fractional photothermolysis for the safe removal of CALMs in individuals with Fitzpatrick skin type (FST) IV-V.

Observations: Retrospective analysis of four patients (FST IV-V) with CALMs revealed that three of these patients had greater than 50% clearance after multiple treatment sessions with the non-ablative fractional 1,550-nm erbium-doped fiber laser. Read More

The description of atomic structure by Niels Bohr set the basis for the emergence of quantum physics. Based on these fundamentals, Einstein published in 1917 a paper on the amplification of energy by Stimulated Emission of Radiation as part of his quantum theories. In 1955, Townes and Gordon turned Einstein's theories into practice, creating a coherent and amplified microwave device using ammonia gas in an optical medium. Read More
